This is an interesting question. I'm a novice rider, just getting back in to the casual riding scene and I've noticed all the goo and stuff that people have on rides, even easy 25-40 mile rides.

I've also noticed that cyclist come in all shapes and sizes.

Do you really think all the supplemental carbs is necessary?
Is a moderate (16-18mph) 2 hour session so gyclogen depleting so as to warrant so much supplementation?
